The role of awareness in the cognitive control of single-prime negative priming.

Summary of "The role of awareness in the cognitive control of single-prime negative priming."

Single-prime negative priming refers to a phenomenon whereby repeating a single prime as a probe target slows responses to that target. This phenomenon is modulated by cognitive control when the contingency between the prime and probe target is higher than chance. The present study investigated the role of prime awareness and awareness of the contingency within the control mechanism during single-prime negative priming. Results showed that while single-prime negative priming occurred regardless of participant awareness, the control mechanism was modulated by prime awareness and perceived contingency.

Cognitive control over conflict, mediated by the prefrontal cortex, is an important skill for successful decision-making. Although it has been shown that cognitive control may operate unconsciously, i...

Task switching refers to the demanding cognitive control process that allows us to flexibly switch between different task contexts. It is a seminal observation that task switching comes with a perform...

Adjustments in cognitive control, as measured by congruency sequence effects, are thought to be influenced by both external stimuli and internal goals. However, this dichotomy has often overshadowed t...

Priming studies investigating the processing of emotional faces under conditions of limited awareness have shown that people can extract more than just valence from masked faces. However, previous res...

Persistent Vegetative State

Vegetative state refers to the neurocognitive status of individuals with severe brain damage, in whom physiologic functions (sleep-wake cycles, autonomic control, and breathing) persist, but awareness (including all cognitive function and emotion) is abolished.

A psychological state of awareness, the practices that promote this awareness, a mode of processing information and a character trait. As a therapy mindfulness is defined as a moment-to-moment awareness of one's experience without judgment and as a state and not a trait.

Executive Function

A set of cognitive functions that controls complex, goal-directed thought and behavior. Executive function involves multiple domains, such as CONCEPT FORMATION, goal management, cognitive flexibility, INHIBITION control, and WORKING MEMORY. Impaired executive function is seen in a range of disorders, e.g., SCHIZOPHRENIA; and ADHD.

Cross-priming

Class I-restricted activation of CD8-POSITIVE LYMPHOCYTES resulting from ANTIGEN PRESENTATION of exogenous ANTIGENS (cross-presentation). This is in contrast to normal activation of these lymphocytes (direct-priming) which results from presentation of endogenous antigens.
